I just endure it and try to stay awake. Sometimes I literally fall asleep for a split second if I stop concentrating on staying awake it gets pretty bad lol. But some of my teachers give us a break for like 5 mins to walk around or get something to eat or drink which is great to get rejuvenated again I find myself surprisingly attentive and awake after that.

i try really hard to stay awake. i might sneak some snacks to get some energy. onbreak in college id grab an energy drink but it didnt really help walking around is good. once there was no way id be ableto stay away so i propped up my big textbook and a short nap. it was in french class in high school

lol I was reading some of the posts
I would try to stay awake by willpower it works sort of..lol
drinking water helps too...and i guess snacks but I would just try to pinch myself awake and trust me pain doesnt help it actually made me sleepy...
doodling helps too :)

Sleep they ain't teaching anything that applies to the real world anyways, sleep through the racket your parents have forced you guys to attend to each day that their too ****ing stupid to understand why someone who is young cannot sit still like a 50 yr old for 8 hrs a day learning nothing except half baked lessons with watered down facts.
